4 Claims.

necting the stays or adjusters from either the window frame or the storm window, or screen, as the case may be. In some instances it is best to disconnect from the storm window or screen leaving the stay on the window frame and in other cases it may be desirable to disconnect,

at the window frame so that the sta will remain with the storm window for storing. The latter is true of course where either no screens are used or where it may not be desired to use a stay with the screen.

The primary object of my invention is to provide a window stay having means for convenient disconnection from the window frame without the use of any tools and to provide a stay having means for as convenient disconnection from the storm window or screen. Another object is to provide window hardware of this kind in simple, durable, inexpensive and neat form.

These and other more detailed and specific objects will be disclosed in the course of the following specification, reference being had to the accompanying drawings, in which Fig. 1 is a side elevation of my stay or adjuster showing the same as mounted on a window frame and storm window (only portions of which are shown) and with the form window swung outward some distance from the frame.

Fig. 2 is a plan view of the stay alone.

Fig. 3 is an elevational view of the frame mounting device alone.

Fig. 4 is a vertical section along the line 4--4 in Fig, 1.

Fig. 5 is an inside elevation of the mounting device of Fig. 3.

Fig. 6 is a view similar to Fig. 1 but showing a modified form of my stay or adjuster.

Fig. '7 is a plan view of the stay of Fig. 6.

Fig, 8 is an enlarged fragmentar section along the line 88 in Fig. 6.

Fig. 9 is a fragmentary side elevation of one end of the stay of Fig. 6 showing the locking member swung to a position for disconnecting the stay from the storm window or screen.

Referring now more particularly and by reference characters to the drawings, I here have shown a window stay designed to connect a lower portion of a closure member such as a storm window or screen A to the window frame B. A stay may be used at each side of the window as will be evident, but in this description only one stay for one side of the window will be set forth in detail since such minor changes as required for right and left hand use will be apparent.

As shown in Figs. 1 through 5 the stay, designated generally at C, comprises an articulated foldable brace made up of inner and outer arms or members Ill and pivotally connected at meeting ends by a pivot bolt l2. The outer end of the arm II is also pivotally connected by a pin l3 to a bracket M which may be secured, as by screws I5, to the storm window (or screen) A and which has an inwardly turned ear l6 for the pin 13.

The fastening for the inner arm or member l0 comprises a plate or mounting I! having screw holes l8 at upper and lower ends through which screws I9 may be passed for securing it to the inside of the window frame B. Atsubstantially a medial portion the plate I! has a keyhole-shaped opening or slot having a relatively narrow lower end 20 and larger upper end 2|. A pin 22 is fixed to the extremity of the inner brace arm l0 and is of such diameter that it may be entered easily into the large upper end 2| of the slot, while the pin has a diametrical groove 23 which may then be slipped downwardly over the vertical margins of the narrow end 20 of the slot to pivotally engage the same. In this position a head portion 24 of the pin fits within, or on the side of, the plate I! toward the frame B, and to provide clearance the plate is preferably pressed to the dishshape shown so as to provide a recess 25 to clear thishead 24 and other parts.

A flat spring 26, constituting a keeper or latch member, is riveted or otherwise fastened at 21 to the inner side of the plate l1 and extends upwardly within the slot in the plate, the upper end of the spring being bent outward at 28 through the upper end of the slot in the plate and then turned upwardly in the form of a finger piece or car 29 which is serrated or knurled as shown. A lug 30 is punched from the spring 26 in such position that it will, as shown in Fig. 4, engage the upper side of the head 24 of the pin 22 when the same is entered in the slot.

In operation the bracket l4 and plate H are secured to the storm window A and frame B, respectively, as described and shown and when the in the flange storm window is put up the stay C is connected by inserting the pin 22 in the upper end 2| of the slot in plate i1 and then forcing it downwardly until the groove '23 engages lower margins of the slot. In this operation the pin 22 cams over the lug 3t forcing the spring 26 inwardly as the pin passes and then, as the pin clears the lug the spring again returns outwardly so that the lug prevents upward displacement of the pin and disconnection of the stay. Of course the stay may be readily disconnected from the plate II, when the storm window is taken down, simply by pressing upon the finger piece 29 until the pin 2'2 may clear the lug 3t and then lifting the pin from the slot in the plate.

When thus mounted the stay C will operate in usual fashion, unfolding and extending outward as the storm window is swung outward to hold it in this position and jackknifing to a folded position when the storm window is closed tight against the window frame.

The lateral margins of the spring 2% may be turned or rolled as shown at 3% in order to afford rigidity at this part of the spring. In any event the spring is arranged and adapted to engage the head portion is of the pin as the same rests in the slot in plate it. Added friction is thus provided and rattling of the parts prevented.

In the folding and unfolding operation of the stay the arms or members and Ii of course pivot about all three pivots i2, i3, and 22, but the center joint or pivot I2 is made adjustable in tension or resistance so that the stay may have sufficient rigidity to hold the storm window in adjusted position. The inner arm ii] is a single, flat strip of material having a pressed longitudinally extending stiffening rib '32 but the outer arm if has an upper edge turned over at right angles in the form of a flange 33. Ifhe meeting ends of the arms it! and H overlap and are apertured to receive the bolt i2, and, at each side of the end of the inner arm, hard rubber, fibre, Bakelite, or similar washers 3% are placed on the bolt. The head of the bolt, having a squared shank 35, is placed through the squared hole in a washer 3t and this washer is locked against rotation relative to the member if! 'by a lug 37 on the washer engaged with a notch 33 The nut 39 is placed on the inner end of the bolt and when drawn up tight against the arm M will cause pressure against the'washers' 34! to provide conveniently adjustable resistance to pivoting movement at this joint. Since the bolt 52, washer 3%, arm H and nut 39 all must turn as a unit, there is no tendency for the nut to loosen as will be evident. The notch 38 is deep enough to provide sufficient play for the washer 3% in making this adjustment.

A radially extended stop shoulder fill on the member it engages the end 4! of the flange 33 to limit unfolding movement of the stay and prevents the arms it and ii from reaching the aligned position from which they might fold in the direction (downward) opposite to that desired.

A fibre, plastic, or Bakelite washer 32 may be arranged between the outer end of member ii and the bracket ear it to provide stiffness or resistance at this point also.

Referring to Figs. 6 through 9, I have shown therein a, modification of my stay .or adjuster represented generally at C and shown as connectedbetween a storm window (or screen) A and window frame B. This stay comprises inner and outer arms or members 43 and 44 pivotally joined at meeting ends by a bolt 45. In this case, however, the inner arm 44 is pivoted, as by a rivet it, to a bracket 41 which may be secured by screws 43 to the window frame B to provide a mounting for the stay, the said bracket being pressed to cause its center portion 49 to stand outward from the frame and a friction washer 56 being provided between the arm and bracket to prevent looseness at this joint.

The outer arm 44 carries a rigidly mounted pivot pin 5| near its outer extremity adapted to be pivotally received in the apertured ear 52 of a bracket 53 which is secured by screws 54 to the storm window A. A latch member 55 is pivotaily mounted by a rivet or pin 55 to the arm 44 and at one end 57 this latch member is offset at 5f! from the adjacent surface of the arm a distance sufficient to just clear the bracket ear 52. This end 5'! is rounded off at its extremity 59 on a radius centered on the axis of the rivet and is so dimensioned that it will enter a groove or slot 63 cut in the adjacent side of the pin 5! in which position the latch member will obviously prevent the disengagement of the pin from the bracket 53. The other end of the latch member 55 is folded and creased to provide an operating portion iii and the arm 44 has a boss 62 pressed inward in position to be engaged by the parallel folded margins 53 of this end of the latch member.

In operation the stay is mounted as described by fastening the brackets t? and 53 to the window frame and storm Window and then, as the storm window is put up, the pin 55 on the outer arm M is inserted through the bracket ear 52 and the latch member turned to a position parallel with the arm so that its end 57 enters the groove 5% and overlies the ear 52 to maintain the pivot connection at this end. The stay will thenfold or unfold as requir d to open or close the storm window. When the storm Window is to be taken down the latch member is swung aside to the position shown in Fig. 9 Where its end 5i clears the ear 52 to allow the pin 5! to be withdrawn therefrom and the window may then be removed and replaced with the screen which may, if desired, be provided with a bracket like 53 for connection with the stay.

In operating the latch member 55 its end 6! must be forced across the 'bOSs 62 which thus prevents accidental swinging movement of the latch such as might free the ear of the bracket. The end 53 of the latchm-ember may be slightly crimped or bent about a center line 53 so that it has a tendency to center itself in the groove to further guard against accidental displacement of the parts.

The meeting ends of the arms 43 and 54 overlap to receive the center pivot bolt 25 and hard rubber orsimilar washers 55 3 are placed between these ends and between the headfifi of the bolt and the adjacent arm so that by drawing up the nut adjustable tension or resistance may be providedat this joint as and for the purposes previously described. The outer arm 44 has a flange ii? along one edge and the inner arm has an extended finger 63 adapted to engage an end of this flange to limit the unfolding action of the arms as will be clearly evident.

Obviously by my invention a window stay may be disconnected at either end from the storm window, screen, or window frame, as may be desired, and this action may becarried out quickly and conveniently Without the use of anytools.

It is understood that suitable modifications may be made in the structure as disclosed, provided such modifications come within the spirit and scope of the appended claims. Having now therefore fully illustrated and described my invention, what I claim to be new and desire to protect by Letters Patent is:

'1. A window stay for detachable connection at one end to a window element, comprising an arm, a pin on the arm, a mounting plate secured to the window element and having a keyholeshaped slot, the said pin being adapted for endwise entrance through the wider end of the slot and having a. circumferential groove for pivotal engagement with the margins of the narrow end of the said slot, a spring secured to an inner side of the plate and extended at one end outwardly from the plate for manual operation, and a lug on the spring for engagement with the pin to prevent movement of the same from its pivotal engagement with the narrow end of the slot.

2. A window stay for detachable connection at one end to a window element, comprising an arm, a pin on the arm, a mounting plate secured to the window element and having a keyhole-shaped slot, the said pin being adapted for endwise entrance through the wider end of the slot and having a circumferential groove for pivotal engagement with the margins of the narrow end of the said slot, the said groove being spaced from the end of the pin to thereby provide a head portion on the pin which in use is disposed on the inner side of the plate, and a spring member secured to an inner side of the plate and having means for releasably engaging the pin to prevent its displacement in the narrow end of the slot, the margins of the spring member being bent to engage the plate and cause the member to stand in spaced relation therewith sufiiciently to substantially clear the head portion of the pin.

3. A window stay comprising a jointed arm, brackets for pivotally connecting opposite ends of the arm to a frame and sash, respectively, one of said brackets being in the form of a concave plate adapted to be securedwith its edged side to the frame and having a key hole slot opening outwardly from the frame, the adjacent arm end having a headed pin for insertion in the slot, a spring keeper secured to and within the said bracket, for releasably engaging the headed pin, and means operative exteriorly of the bracket, for actuating said keeper to release the pin.

4. A window stay comprising a stay arm attached at its outer end to the window, a bracket for releasably attaching the inner end of the arm to the window frame, said bracket being formed of a dished plate secured with its concave side to the frame, the body of the plate having a slot and the inner end of the arm having a pin for removable engagement in the slot, a spring keeper secured to and within the concave side of the bracket to releasably engage said pin, and means extending exteriorly of the bracket for actuating the keeper to release the pin and thereby disconnect the adjacent end of the stay arm from the bracket.
